Garage Apartment Services in Dallas–Fort Worth

Typical Cost

Garage Conversions
Turn your existing attached or detached garage into fully livable, climate-controlled space. One of the fastest and most cost-effective ways to add square footage to your property. We handle insulation, plumbing, electrical, and finish-out — making it feel like a seamless part of your home.

Above-Garage Apartments
Build a full apartment above your existing or new garage — separate entrance, full kitchen and bath, designed for independent living. Because the garage already provides the foundation and structural support, costs are often lower than a fully detached build.
Typical Timeline
4–7 months
Typical Cost
$80,000–$200,000

Homeowners who want to keep their garage and add a complete independent living unit above it.
Typical Cost

Detached ADUs
A standalone structure on your property — designed from scratch, built from the ground up, and completely separate from your main home. Because it's a new build, you have total control over the design: layout, size, placement, and finishes. The most flexible option for homeowners who want true independent living space.
Typical Timeline
5–9 months
Typical Cost
$100,000–$300,000+
Best For
Homeowners with available lot space who want a purpose-built, fully independent structure.

$80,000–$250,000
Guest Houses
Whether it's for aging parents, visiting family, or long-term guests — a guest house adds flexibility and lasting value to your property. We design them to complement your primary home's architecture, with the same luxury finishes and attention to detail that define every 6th Ave Homes project.
